Recurrent tracheoesophageal fistula in an adolescent without persistent symptoms: A case report.

RATIONALE: Congenital esophageal atresia (EA) and tracheoesophageal fistula (TEF) ininfants have been treated well with surgery. Approximately 10% of children displayed recurrent fistula. In the present case, we reported recurrent TEF in an adolescent as a complication of EA/TEF in infancy. PATIENT CONCERNS: An infant was diagnosed with gross type C congenital EA and TEF and subsequentlyunderwent repair in early infancy, with division of the TEF and primary esophageal anastomosis. Postoperative esophageal strictures developed and were relieved by bougienage of the esophagus partially. Then, the child had normal growth with mild symptoms, mainly choking when drinking water. At 11 years of age, the child developed fever and cough, and massive bronchiectasis in lobus inferior pulmonis sinister was found. DIAGNOSIS: Recurrent tracheoesophageal fistula.
INTERVENTIONS: Division of the TEF and esophageal replacement with gastric tube was performed as treatment OUTCOMES:: The child recovered well. LESSONS: Recurrent tracheoesophageal fistula aftercongenital EA and TEF could be diagnosed in adolescence. Massive bronchiectasis might develop without apparent symptoms.

Introduction

Congenital esophageal atresia (EA) and tracheoesophageal fistula (TEF) in infants have been treated well with surgery.[ Approximately 10% of children with a history of EA and TEF display recurrent fistula.[ Notably, the recurrent fistula in adolescents was very scarce, since its relevant symptoms are apparent. In the present case, we report a recurrent TEF in an adolescent as a complication of EA/TEF in infancy. The child displayed milder symptoms and normal growth, which delayed the diagnosis of this complication.

Case presentation

An infant was diagnosed with gross type C congenital EA and TEF and subsequently underwent repair in early infancy, with division of the TEF and primary esophageal anastomosis. Postoperative esophageal strictures developed and were relieved by bougienage of the esophagus partially. Then, the child had normal growth with occasional mild symptoms, mainly choking when drinking water. At 11 years of age, the child developed fever and cough that were not relieved after routine treatment. Subsequently, computed tomography (CT) scan illustrated massive bronchiectasis in the lobus inferior pulmonis sinister (Fig. 1A). In order to evaluate the bronchiectasis, bronchofiberoscopy was performed, and a TEF was found. Methylenum coeruleum stain and passage of barium confirmed TEF (Fig. 1B–D). Division of the TEF and esophageal replacement with gastric tube was performed as treatment, and the child recovered well. This study was approved by the Clinical Ethics Review Board at Guangzhou Women and Children's Medical Center. A written informed consent was obtained from the patient and the parents at the time of admission.

Discussion

The incidence of recurrent TEF was reported to be 5% to 14% after surgical repair of esophageal atresia.[ It usually develops within 18 months after the initial surgery with rare cases developing years later.[ Currently, this complication is likely to decrease with the improvement of surgical instruments and imaging and surgical techniques. In the present case, the adolescent was diagnosed with recurrent TEF 11 years after the initial surgery. The recurrent fistula was not a second congenital fistula located in the pouch of the original fistula, which was suggested by bronchoscopy prior to the original TEF surgery. Recurrent fistula is more common after a primary esophageal repair under tension,[ with ligation instead of complete division. Recurrent TEF may be suspected when a child presents with repeated lower respiratory tract infections with a history of EA. The adolescent in our study presented mild symptoms that delayed the diagnosis. However, the delay did not affect the growth of the adolescent. At 11 years of age, persistent symptoms of pneumonia and massive bronchiectasis lead to the performance of bronchofiberoscopy, which finally diagnosed the recurrent TEF.

This is a rare case of recurrent TEF, whose symptoms were very mild and did not influence the development of the adolescent. However, massive bronchiectasis developed in this adolescent. Thus, bronchofiberoscopy for children with history of EA might be necessary for early detection of recurrent TEF even years after surgery.
